[A case of angiosarcoma of the pelvis associated with angiomatosis of the spine].

Primary angiosarcoma of the bone is an infrequent lesion and it is seldom associated with other bone lesions, i.e. only two cases have been informed related with skeletal angiomatosis. We present the case of a 62 year old woman who complained of a gluteal tumor and disability to walk 11 months before death. In the autopsy an angiosarcoma originated from the bones of the pelvis was found. It eroded and destroyed the iliac bone and acetabulum, and extended to the soft tissues of the gluteal region and the retroperitoneum, with renal capsule metastases. Angiomatosis of the vertebral bodies was identified.
